Opera 10.60 has been released July 1 for Mac OS X and is available for download. The features highlighted on the changelogs page are: layout engine (codename 'Presto'), HTML5 with support for offline web applications, WebM, which has been available in Opera (in a special build) on the very day of the announcement at the Google I/O conference, web workers for running scripts in the background without impeding the browsing experience, and geolocation. Version 10.60 is also available for Windows and Linux/BSD.

You are misunderstanding the problem. The problem is that there is nothing stopping opera software from placing glibc or openssh-server packages on their repo and then those opera's unofficial versions would be installed on all opera users' computers.

Indeed, they could. But why would they? Tell me even one good reason why would they start to maintain such packages when it provides them with no benefit whatsoever, only extra work to do? It's simply not in their best interest to do the extra work, make sure their packages are free of security holes, are patched properly, work in all the intended distros and then even keep them up-to-date when the distros themselves already have processes and people set up to do that work.

So if I run a booth that copies keys, and you come there to get a copy of your house key, should I keep a copy of your key, without telling you about it, and even installing my own fancy monitoring system that notifies me of when you change your locks? After all, it would make it easier for you to get a second copy of your house key, and it would enable me to provide you with updated keys when you change locks. And why would I want to use my secretly copied copy of your key for anything bad?

The point is that opera software should not go mucking around in the most important system settings without the user explicitly telling them to do it. (Similarly, I should never make a copy of your house key without you explicitly telling me to do it.)

Err. How is that even remotely similar to a repository? They don't get your keys, they don't know what software you have installed, they don't monitor you. Do explain, I am all ears.

Again, they don't have your key, you have their key. Quite different. And in your (rather stupid) example you'd have access to a single house, whereas Opera's repo is accessed by thousands. If something was screwy it'd be noticed whereas if you broke to a single house it'd be noticed by only a handful of people and they wouldn't know who it was.
